Given:
The equation of a parabola is:
[tex]y=-2x^2+7x+4[/tex]
To find:
The vertex of the graph of the given equation by using a graphing calculator.
Solution:
We have,
[tex]y=-2x^2+7x+4[/tex]
By using the graphing calculator, draw the graph of the given equation as shown below.
From the below graph it is clear that the function is maximum at point (1.75,10.125).
So, the vertex of the given equation is (1.75,10.125).
Therefore, the correct option is c.

[tex]\sqrt{306} = 17.5[/tex]
Answer:
x ≈ 17.5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² = 9² + 15² = 81 + 225 = 306 ( take the square root of both sides )
x = [tex]\sqrt{306}[/tex] ≈ 17.5 ( to the nearest tenth )

−9x (5x+4 ) +10 (x+3) can someone please solve his for me thank u step by step please i really need to find out how to do it
Answers
Answer:
-45[tex]x^{2}[/tex]-26x+30
Step-by-step explanation:
So first you let's divide this equation into three parts.
Part one -9x(5x+4)
Step one: you have to distribute the -9x to the numbers in the parentheses. That would leave us with a -9x*5x = -45[tex]x^{2}[/tex] and -9x*4 = -36xStep two: Put the answers together. That would leave us with -45[tex]x^{2}[/tex]-36x.
Part two 10(x+3)
Step one: you have to distribute the 10 to the numbers in the parentheses. That would leave us with a 10*x = 10x and 10*3 = 30Step two: Put the answers together. That would leave us with 10x+30
Part three solve
Step one: combine and put together what you have solved for. That would leave us with a -45[tex]x^{2}[/tex]-36x+ 10x+30 Step two: combine like terms. The like terms here are -36x and 10x. When you combine them you would get -26x.Step three: Write the equation in standard form. Therefore the answer is -45[tex]x^{2}[/tex]-26x+30.

line that shows 8, shows that each of six sides is 8
so that's 48
to get the "apothem"
it means get a side of the triangle where the hypotenuse is 8 and the base is 4 (half of 8)

Which function describes the vertical shift up 2 units and left 2 units to the original function: f(x) = ex
Answers
Answer:
g(x) = e^(x + 2) + 2
Step-by-step explanation:
First, let's describe the shifts.
Vertical shift.
For a function f(x), a vertical shift of N units is written as:
g(x) = f(x) + N
If N is positive, then the shift is upwards.
If N is negative, then the shift is downwards.
Horizontal shift.
For a function f(x), a horizontal shift of N units is written as:
g(x) = f(x - N)
If N is positive, the translation is to the right
If N is negative, the translation is to the left.
Now let's solve the question.
f(x) = e^x
First, we have a vertical shift up of 2 units, then:
g(x) = f(x) + 2
Now we have a shift to the left of 2 units:
g(x) = f(x - (-2)) + 2
g(x) = f(x + 2) + 2
Then:
g(x) = e^(x + 2) + 2

Answer:
Hey love! x = 6
Step-by-step explanation:
because 13 x 6 = 78
HOPE THIS HELPS!
Answer:
x = 6
Work -
13x = 78
divide 13 on both sides to isolate x. 78 divided by 13 gives us 6, and 13/13 =1.
1 times x is x, as you can see, we have isolated x on one side. On the other side, we got 6, so x = 6

Every two out of three kids sang at the talent show. What percent of the kids did not sing at the talent show? (round)
Answers
66.7 %
convert to decimal the multiply by 100
33.3% do not sing in the talent show.
What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of kids = 3
Number of kids who sang = 2
The number of kids who do not sing.
= 3 - 2
= 1
The percentage of kids who do not sing.
= 1/3 x 100
= 33.33%
Thus,
33.3% do not sing in the talent show.

In cabbage butterflies, white wings (W) are dominant to yellow wings (w). A heterozygous butterfly mates with a butterfly that has yellow wings. Complete the Punnett square and then list the percentages of the expected genotypes for their offspring.
Answers
Answer:
(a)
[tex]\begin{array}{ccc}{} & {W} & {w} & {w} & {Ww } & {ww } & {w} & { Ww} & {ww } \ \end{array}[/tex]
(b)
[tex]White = 50\%[/tex]
[tex]Yellow = 50\%[/tex]
Step-by-step explanation:
See attachment for initial punnet square
Solving (a): Complete the square
Initially, we have:
[tex]\begin{array}{ccc}{} & {W} & {w} & {w} & { } & { } & {w} & { } & { } \ \end{array}[/tex]
To complete the square, we simply write the letter at the column and the letter at the row in each cell;
So, we have:
[tex]\begin{array}{ccc}{} & {W} & {w} & {w} & {Ww } & {ww } & {w} & { Ww} & {ww } \ \end{array}[/tex]
Solving (b): Percentage of each
From the question, we understand that W are dominant to w.
So:
[tex]Ww = White[/tex]
[tex]ww = Yellow[/tex]
From (a) above
[tex]Ww = 2[/tex]
[tex]ww = 2[/tex]
[tex]Total = 4[/tex]
So, the percentage of each is:
[tex]White = \frac{Ww}{Total} * 100\%[/tex]
[tex]White = \frac{2}{4} * 100\%[/tex]
[tex]White = 0.5 * 100\%[/tex]
[tex]White = 50\%[/tex]
[tex]Yellow = 100\% - White[/tex] --- Complement rule
[tex]Yellow = 100\% - 50\%[/tex]
[tex]Yellow = 50\%[/tex]
